About E50.2

E50.2 is the ICD-10-CM diagnosis code for vitamin A deficiency with corneal xerosis. It belongs to category E50 (vitamin A deficiency), block E50-E64 (other nutritional deficiencies) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E50 (vitamin A deficiency), E50.2 is specifically for vitamin A deficiency with corneal xerosis. Related codes cover with conjunctival xerosis (E50.0), with Bitot's spot and conjunctival xerosis (E50.1), with corneal ulceration and xerosis (E50.3), with keratomalacia (E50.4), with night blindness (E50.5), with xerophthalmic scars of cornea (E50.6), other ocular manifestations of vitamin A deficiency (E50.7), other manifestations of vitamin A deficiency (E50.8) and 1 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 264.2 (vitamin A deficiency with corneal xerosis).
